So people say you can't use ISO 25600. Last night I shot this photo at that ISO and a shutter of 6 seconds just to test location before I dropped the ISO to 6400 for the real shots. When I checked the shot out on the computer, I really liked it and the noise wasn't so much that I couldn't clean it up a bit in LR. Granted night skies are a little easier to deal with and the photo isn't perfect, but this is about as much noise as I would get with my T2i at ISO 1600!

The 6D is really impressive with high ISO. I have quite a few perfectly usable shots at ISO 25,600 and don't hesitate to use it. I just sold a fine art print last week that I shot at 25,600.

How do you link a picture from Smugmug into this post and being able to see the picture.I am new to this posting stuff.

You click on the picture in your Smugmug site, select a decent size image (like X2 or X3), then right click on the picture and select "Copy Image Location" or something similar, depending on your browser. Then when you create your CR post, click on the "Insert Image" button in the toolbar (little framed Mona Lisa) and paste the photo URL in between the img brackets. If you want to add a link to your gallery page below that, copy the address of the SmugMug web page from the browser address bar and then use the "Insert Hyperlink" button in your CR post. The same process should work for Flicker and other photo sharing sites.

I have tried attaching images to posts here, but I've never been happy with the color of the rendered jpegs, whereas embedding a SmugMug link preserves my color management settings.
